gRPC with Dagger

gRPC is an open-source RPC framework from Google. Its Java library lets you create RPC servers by implementing interfaces that are generated from Protocol Buffer files, and provides client stub implementations.

Dagger-gRPC is an extension to Dagger that lets you use Dagger to create applications that use gRPC.

You can use Dagger-gRPC to create servers.

Call scope

Call scope is a scope that lasts for one gRPC call. A gRPC call comprises one or more request messages and one or more response messages. You can use @CallScoped to bind objects once for the lifetime of one call. On the server, bindings in call scope can inject the headers object for the call.
